ICE-CREAM TUB.

application filed April 2%, 1921. Serial No. lfifltl.

To all whom it may concern:

Be it known that I, l/VILLIAM Wrrrrsnn, a citizen of the United States of America, and resident of Oskaloosa, in the county of Mahaska and State of Iowa, have invented-certain new and useful Improvements in Ice- Cream Tubs, of which the following is a specification.

This invention relates to tubs and particularly to tubs for use in connection with the manufacture of storage of ice cream.

The invention has for its object the provision of a tub having a relatively strong bottom, the said bottom being provided with means to permit the circulation of air, in order to prevent undue expansion due to the accumulation of water in the wood forming body.

It is a well. known fact that ice cream tubs are subjected to rough usage and abuse and they speedily deteriorate. It is an object of the invention to produce a tub of the character indicated comprising a plurality of staves and hoops supplied with a double bottom fitting in different chime grooves.

It is the purpose of this invention to produce a bottom comprising two thicknesses being held in contact by reason of their mounting in the staves, and it has been found in practice that the two sections retain, moisture if kept in contact, whereas a bottom comprising a single piece of the same thickness of the double bottom will dry quicker than a two-piece bottom, a condition which results in the loosening of the joints and the impairment of the tub.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote correspond lug parts in the several views, and in which Figure 1. illustrates a sectional view of a tub embodyingthe invention; Figure 2 illustrates a sectional view at right angles to the section shown in Fig. 1;

Figure 3 illustrates an elevation of Fa fragment of a tub at the bottom;

by hoops 11 which may likewise be increased or diminished in number, according to the strength to be imparted to the tub.

The interior of the tub has chime grooves 12 and 13, the former of which forms a seat for the lowermost section 14 of the bottom, the edge of whichis beveled to the contour of a wall of the chime groove 12. and the latter. of which forms a seat for the upper section 15 of the bottom, which section has a beveled edge shaped to the contour of a ,wall of thechime groove 18. of wood, as stated, the said bottom sections The upper face of the section 14: has a transversely disposed groove or slot 16, and

i the upper section 15, in thepresent embodiment of the invention, has preferably a plurality oftransversely disposed grooves or slots 17. in its under face, and the said sections are placed in the chime grooves in a manner to insure the contact of the upper surface of the section 14: withthe lower surface of the section 15, and the groove in the section 14: is at right angles to the grooves 17 although the angles of intersections of these grooves maybe changed. lhe main purpose. however. in having; these grooves cross each other toeffect a oirculation of air which admitted between the two sections of the bottom, by reason of the fact that the lowermost hoop 11 has apertures such 18 which aline or register with apertures 19 formed in the staves, and the said apertures in the staves in turn register with the slot or groove 16 iii the lower section of the bottom. It follows from the foregoing, that air may therefore pass between the sections from one side of the tub ,to the other, a condition which results in preventing undue accumulation of .jt u re. 5 0

moisture in the bottom and any unequal expansion or swelling of the bottom which would result from its being water-soaked. This construction will furthermore prevent the bottom from rotting, as it will prevent the retention of water in the bottom when the tub is not in use. i The inventor h: found that a tub made in accordance with the invention, theupper section of the bottom retains the contents of the tub, whereas the ventilating spaces relieve the tub of seepage. The lowermost section ofthe bottom also braces the upper section and serves to assist in resisting the inside load pressure which is often very great, especially when the tub is being shipped or handled during its transfer. Tubs of this character are often dropped Whenbeing pulled from a conveyance to a sidewalk, station, platform. or the like, and as the lowermost section of the bottom is flush with the lower ends of the staves, the staves and bottom present a smooth surface from the lower edge of the bottom hoop to any side across the staves and bottom.

In providing means for draining the tub, the flangedtube 20 is employed, which extends through a' threaded aperture 21 in thestaves, the saidtube being anchored in place by reason of the threads 22 -formed on itsouter surface. The outer surface of the tub is preferably recessed, as shown at 23, to form a seat for the flange 24 of the tube. as by this arrangement, no projection is afforded which might interfere with the proper packing or handling of the tub. The t'ube 22 aside'from its being threaded in the staves is also secured at its inner end by a ringnut or washer 25 threaded on the tube and bearing; against the inner surface of the tub. It is a well known fact that when drain plugs are applied to or removed from unprotected tubs, the wood forming the tub is soon bruised and caused to disintegrate, making; it necessary to more tightly drive the plug practically with each of its applications to the drain aper- A. bushing 26 of non-corrosive material. is inserted in the tube with its outer end preferably flush withthe outer end of the tube and said bushing is shorter than the tube .to'which it applied. but preferably this bushing; is secured in place by threads 27. 'The "purpose or havinig the bushing .i'elativel'y short is to permit the plug or stopper to be oscillated sidewise while it is being loosened for." removal. As the bushing is relatively short, lateral impact on the outer GllClOlf the plug or stopper would result in a slight lateral movement in the bushing, and whenfthis is repeated several times, the stopper will become dislodged. Byreason of the tact thatth e bushing is screwed in place, it can be readily removed for the purpose of sul'istituting a new onc, and hence the tub can be maintained at a high deg c of clliciency with respect to its draining facilities without impair-in the tub structure as a whole.

The handle which is employed in connection with the tub preferably compriscs a plate 28, which is inserted or set in a. l'cccr s formed in the stave or stares. handle pintle 29 has its upper surface shouldered. as shown at 30, and the said pintlc has straight sides Ell and a curved lower side 231'". The handle 31 is of the ordinary loop type and it has an aperture 2-32 to receive the pinllc. the wall ol the aperture at lhc upper side lravinga longitudinal recess or seal to allow the handle to seat on the pintlc. The fact that the handle when swung: into the housing has a slot or recess which permits the handle to tall or descend until the pintle lies in the said seat or recess. results in the retention of the handle in its 'l'olded position against swinging outwardly as the tub is handled, although, of course, by a sligrhl lifting action on the handle. it can be unseated from the piutle and it is then free to swingto the horizontal position shown in dotted lines (Fig. 8).

The plate 28 has a depending llanpj 28 at its front edge near the top which is intendcd to engage the handle when it is swung outwardly, and the inner end of thc handle beyond the pivot. engages shoulders or lugs 28 formed on the "lace ol the plate. and the said flange and hug: serve to support the load and. remove the load from the pin or pintle, a condition which results in durability.

As shown in the drawing. the plate 28 has a marginal flange A which extends around its edge and it is to be set in a recess formed in the outer surfaces of the slaves, in order that the outer Faces of the flanges will be flush with the outer faces oi. the stavcs to permit the hoops to be applied to the tub by passing over the surfaces of lhe flanges.

It will be noted that the handles and the drain plug shown and described hcrcin are particularly adapted For use with a rcccptac e ol the character sci forth. as lhc ban dles are held in place by the hoops. said handles being: seated in rcccsscs in the slavcs.

also that the drain tube is flush with the stares and is positioncd between the lowcr hoops. to be protected by [be same. 'lhcsc -Features o'l my invention will Form the subject matter ol other applications for licls ters Patent.
